I have this armchair and I would like to put the colored texture, I wanted to know which is the best way, I selected the knits and textured individually, but it was not a satisfactory result.
I would just UV unwrap it and put all the different color textures together. There’s no reason for them to be separated. A normal map would help to get the effect you need for the stitches and the seams.
I could try to help is Portuguese, by message. Maybe it could be better.
